GVO JAOF1003-B Rotating Motor Pressure Relief Valve Hydraulic Safety Valve DH55 DH60-7 Excavator Construction Machinery Parts

Product Description

The GVO excavator relief valve, compatible with DH55 DH60-7 excavators, is a key pressure control valve in the hydraulic system. It regulates hydraulic pressure, releases overload pressure, protects core hydraulic components such as the main valve and hydraulic pump, and ensures stable operation of the entire machine.

This relief valve is precision-machined from high-quality steel and undergoes overall quenching treatment. Equipped with oil-resistant and high-pressure-resistant seals, it boasts excellent sealing performance, impact resistance, and wear resistance. Suitable for the high-pressure hydraulic conditions of excavators, it effectively prevents internal leakage, pressure loss, operational instability, and vibration.

Product Introduction

This relief valve is specially designed for the multi-way distribution valve of the DH55 and DH60-7 small excavators. It is a crucial pressure control component in the hydraulic system, responsible for limiting system pressure and providing overload protection functions.

The valve body is precisely machined from high-quality alloy steel as a single piece. The valve core undergoes quenching hardening and mirror surface grinding processes, resulting in a high surface hardness that resists the erosion and wear caused by hydraulic oil impurities, effectively reducing the risks of valve sticking, sluggish movements, and other faults. It is equipped with high-quality oil-resistant sealing components, which can withstand long-term immersion in hydraulic oil and changes in operating environment temperatures, maintaining stable sealing performance and eliminating problems such as system leakage and pressure drop. The relief valve can precisely limit the maximum working pressure of the hydraulic circuit. When the load exceeds the set value, it automatically opens the relief valve, protecting the hydraulic pump and main valve from damage caused by high-pressure impacts, and can effectively solve common hydraulic faults such as insufficient power, insufficient pressure, abnormal overflow sounds, and stuck compound actions of the excavator.
